1. [techspeak] The action of a counter that starts over at zero or
at minus infinity (see
infinity) after its maximum value has been reached,
and continues incrementing, either because it is programmed to do so or
because of an overflow (as when a car's odometer starts over at 0).

2. To change phase gradually and continuously
by maintaining a steady wake-sleep cycle somewhat longer than 24 hours,
e.g., living six long (28-hour) days in a week (or, equivalently, sleeping
at the rate of 10 microhertz). This sense is also called
phase-wrapping.
